Making an HTTP POST in Groovy From Grails (Groovy Recipies)

I am trying the code obtained from Chapter 9 Web Services from Groovy Recipes and I am getting the following error.

No signature of method: java.io.OutputStreamWriter.writer() is applicable for values: [n=20&vf=pdf&p=groovy+grails]

Here is the code:
def queryString = []
queryString << "n=" + URLEncoder.encode("20")
queryString << "vf=" + URLEncoder.encode("pdf")
queryString << "p=" + URLEncoder.encode("groovy grails")

def url = new URL("http://search.yahoo.com/search")
def connection = url.openConnection()
connection.setRequestMethod("POST")

connection.doOutput = true
Writer writer = new OutputStreamWriter(connection.outputStream)
writer.writer(queryString.join("&"))
writer.flush()
writer.close()
connection.connect()
println connection.content.text

Can someone help me determine what is wrong?

I think it might be the following line:

writer.writer(queryString.join("&"))

I think it is suppose to be:

writer.write(queryString.join("&"))

RE: Making an HTTP POST in Groovy From Grails (Groovy Recipies)

FYI, you can also accomplish the following:

URLEncoder.encode("20")

Like this:

"20".encodeAsURL()

See here for the relevant documentation: http://grails.org/doc/1.1.x/guide/single.html#11.2%20Encoding%20and%20Decoding%20Objects

Re: Making an HTTP POST in Groovy From Grails (Groovy Recipies)

<shameless self-promotion>
You can also use HTTPBuilder to easily POST data to other web servers
from Grails. Then you don't have to muck around encoding the post
body yourself. See:
http://groovy.codehaus.org/modules/http-builder/doc/post.html
